Saying that something is impossible is easy. Demonstrating that, not so easy. Remember, you cannot use the absence of evidence to support impossibility, which is why you were asked about improbability, which is, I think, much more apt.
My mind is open to whatever has evidence supporting it, in direct proportion to the quality and quantity of said evidence. If that leads me to the improbable, so be it. I don't like claiming knowledge I don't actually possess, and that's not a matter of fear, but honesty.
